Centralized energy metering device embedded with information security module and Internet of Things system

Abstract

The invention discloses a centralized energy metering device embedded with an information security module, which comprises a natural gas data acquisition system, a calorific value analysis processing system and an energy calculation module, and is characterized in that the energy calculation module is also connected with a communication module, and the communication module is used for sending communication data; an information security management module is also arranged between the communication module and the energy calculation module; and the information security management module is used for carrying out information interaction object identity authentication, interaction data encryption and decryption and interaction data integrity and validity verification on the communication data. According to the invention, the information security management module is added between the energy calculation module and the communication module to effectively encrypt and decrypt the communication data, so that the communication data of different users are effectively distinguished, and the difficulty of summarizing and sorting the communication data by a service institution is reduced.

Description

technical field [0001] The invention relates to the field of natural gas energy metering, in particular to a centralized energy metering device embedded with an information security module and an Internet of Things system. Background technique [0002] As a high-quality, high-efficiency, clean energy and important chemical raw material, natural gas has been widely valued and used preferentially in all countries in the world, accounting for 35% of the energy structure. With the continuous rise of the status of natural gas as an environmentally friendly energy source, accurate, fair and just measurement of natural gas is an important technical work for scientific management of natural gas, which is related to the interests of many parties. At the same time, as natural gas is used as a fuel, its actual value should be its calorific value rather than its volume. Foreign natural gas measurement methods generally use energy measurement methods, so it is inevitable that unnecessary...
